SPECIFICATION forming part of Letters Patent No. 457,179, dated August4, 1891.

Application filed March 26, 1891.

To all whom it may concern:

Be it known that we, SAMUEL W. BUENCE and JOHN SOHUETZ, of Argentine,Vyandotte county, Kansas, have invented certain newandusefullmprovementsinSaw-Sets, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

Our invention relates to appliances for impartingthe required slant tothe teeth of bandsaws so that the kerf or cut made by the saw shall bewider than the thickness of the saw; and the objects of our inventionare to provide a saw-set which shall operate with great rapidity touniformly set the teeth of the saw and which shall be caused to operatesimply by therevolution of the saw; furthermore, to provide a saw-setcertain parts of which shall be removable and interchangeable, so as toadapt the appliance to operate upon saws of diiferent sizes and upondifferent types of saw-teeth.

-To the above purposes our invention con sists in certain peculiar andnovel features of construction and arrangement, as hereinafter describedand claimed.

In order that our invention may-be fully understood, we will proceed todescribe it with reference to the accompanying drawings, in which Figure1 is a side elevation of our improved revolving saw-set. Fig. 2 is aplan view of the same. Fig. 3 is a vertical longitudinal section of thesame on the line 3 3 of Fig. 2. Fig. 4 is a transverse vertical sectionof the same on the line 4. at of Fig. 2. Fig. 5 is a cross-section ofthe two setting-disks on the line 5 f Fig. 2, the said disks beingremoved from their supporting-standards. Fig. 6 is a. detachedperspective View of the slide which carries the backing-wheel. Fig. 7 isa detached perspective view of one of the sawguides. Fig. 8 is aperspective view of the upper front portion of the slide-support, showing the guides for the sliding saw-guides. Fig. 9 is a detachedperspective view of the removable axle of the setting-disks. Fig. 10 isa detached perspective view of one of the connecting-bolts for thesetting-disks.

In the said drawings, 1 designates the base Serial No. 386,520. (Nomodel.)

of the saw-set, the said base being of oblong rectangular form and beingprovided with a long recess or cut 2, extending longitudinally of thebase and opening at one end of the same, for the purpose to behereinafter explained. Upon the upper side of the base 1 and near to theopposite end of the same from that at which the recesses or cut2 opensare secured two parallel upright standards 3. The upper inner side ofeach of these standards is formed with a horizontal groove 4, each ofwhich opens out of the rear end of the standard and terminates justwithin the front end of said standard, as shown in Fig. 8. These twogrooves lie exactly opposite each other and are designed to receiveelongated tongues or ribs 5 upon opposite sides of a slide 6. This slide6 is bifurcated at its front end, so as to form two parallel arms 7,which are separated from each other by a recess, 8, ex.

the inner end of said rod is reduced to pass...

through an opening in a cross-piece 14, which' connects the twostandards 3 beneath the slide 6. A nut 15 is screwed upon the inner endof the rod 13, so that the cross-piece 14 is confined between said nutand a shoulder on the inner part of the rod 13. The rod 13 also passesthrough a smooth opening in a crosspiece 16, connecting the twostandards 3 at the rear sides thereof and beneath the slide 6, the saidcross-piece serving to support" the outer part of the rod." At its outerend the rod 13 carries a hand-wheel 17.0r an equivalent device by whichto revolve the rod. The backing-wheel 10, above referred to, is formedwith a peripheral groove 18 to receive the back of the saw, as will behereinafter eX- plained.

Upon the front upper corner of each standard 3 is formed a VerticalC-guide l9,the two guides thus being opposite each other,

and through each of these guides works the horizontal outwardlyextendingslide portion 20 of a saw-guide 21. These guides lie opposite to andparallel with each other and are each of elongated form, the inner sideof each guide being formed with a segmental recess 22 to receive theouter part of the backing-wheel 10. To the rear side of each slide 20and at the outer end thereof is bolted a bearing 23, having ascrew-threaded opening 24, while upon the rear side of each guide 19 isbolted a bearing 25, having a smooth opening 26. A screw-rod 27 worksthrough each opening 24 of the slides 20, and its inner end is retainedwithin the opening 26 of the corresponding bearing 25. The outer end ofeach screw-rod 27 carries a handwheel 28 or an equivalent device forrotating said screw-rod; and it will be seen that by turning the saidscrew-rods 27 in one or the opposite direction the guides 21 will bemoved nearer to or farther from each other, for a purpose that will bepresently explained.

Upon the upper side of the base 1, near that end out of which the recess2 opens, are formed or secured two upright parallel standards 29, in theupper ends of each of which is formed a bearing 30. Through thesebearings 30 extends a removable axle 31, which also extends transverselythrough the centers of the two setting-disks 32. Each of these disks 32is formed on its periphery with a number of radial tooth-likeprojections 33 and each of said projections is formed on one side with adownwardly and outwardly inclined surface 34:. These disks are mountedupon the axle 31 side by side, with the projections or dies 33 of onedisk opposite the spaces between the dies 33 of the other disk and withthe inclined surfaces 34 inclined toward each other. In order that thedies of one disk shall always remain opposite the spaces between thedies of the opposite disk, each disk is formed with two lugs 35 and tworecesses or holes 36, and these lugs entering the recesses or holesprevent the disks from revolving past each other. At points oppositefrom the lugs 35 and recesses 36 are two bolts 37, which pass throughthe disks and are each provided with anut 38 and aid in keeping thedisks together with their dies in the described relation to each other.

In using the saw-set the axle 31 is first pushed out of its bearings 30in the standards 29 andthe setting-disks 32 are removed. The base-plate1 is now placed upon the band-saw table and the saw is caused to enterthe recess 2, the base being moved along till the back of the saw entersthe groove 18 of the backing-wheel 10. The setting-disks 32 are nowplaced in position and the axle 31 is pushed into the bearings 30 of thestandards 29 and through the centers of the disks 32. The screw-rod'13is rotated so as to properly adjust the slide 6 to bring thebacking-wheel into proper position, and the screw-rods 27 are rotated soas to bring the guides 21 lightly against the sides of the saw, so thatit will run true, the toothed edge of the saw extending between the dies33 of the disks 32. pulleys which carry it, and as it passes between theguides 21 it rotates the disks 32, the alternate disks 33 coming incontactwith the opposite sides of the alternate teeth of the saw and theinclined surfaces 34 of the dies bending the successive teeth with amovement corresponding with the length of the saw and in oppositedirections so as to give them the required set or slant. The op erationis accomplished with marked rapidity, and a saw can be completely set ina small fraction of the time formerly required. Moreover, it isunnecessary to remove the saw from its working position while its teethare being set, so that a great saving of time and labor is obtained.

It is obvious that a precise form, size, and number of dies for eachdisk are to be varied to accord with different types of saw-teeth, andit will be seen that the adjustable charact-er of the slides which carrythe guides and the backing-wheel enables the saw-set to operate upon thesaws of very different widths and thicknesses.

Having thus fully described our invention, what we claim as new therein,and desire to secure by Letters Patent, isg 1. An improved saw-setcomprising a suitable recessed base, a frame located upon said base, aslide mounted adjustably in said frame and carrying a peripheral groovedbacking-wheel, a pair of guides for the sides of the saw mounted uponadjustable slides working laterally in the frame, screw-rods for movingsaid slides, and a second flame located upon the base and carrying tworemovable revoluble disks having each a number of radially-projectingperipheral dies arranged alternately with relation to each other,substantially as set forth.

2. An improved saw-set comprising a pair of revoluble disks having eachradially-projecting peripheral dies, the dies of one disk being oppositethe spaces between those of the other disk and one of said disks havingprojections on its side to enter recesses in the adjacent side of theother disk, and bolts passing through the disks and serving to Thesaw-band is now moved over the- IIO properly connect said disks,substantially as able frame-work, a slide mounted therein and carryingat its front end a peripherallygrooved backing-wheel for the saw, and apair of saw-guiding slides working in said frame at right angles to thebacking-wheel slide and having each a guide provided on its side with arecess to receive the backingwheel, substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
